Effect of Salt Stress on Antioxidant Enzymes, Soluble Sugar and Yield of Oat

The objective of this study was to evaluate the changing mechanism of soluble sugar, antioxidantenzymes of oat at reproductive stage under salt stress. Two cultivars selected (salt-tolerant Baiyan 2, salt-sensitive. Caoyou 1) were exposed to varied salt concentrations (0, 50, 100, 150, 200 mmol/L, respectively) at seedling stage. The salt was composed by NaCl, Na2SO4 (1:1).
